Prove you’re safe

New from Martindale Electric is the
portable and sleek PD700 Proving
Device, designed for the testing of
contact voltage detectors up to 700V.

The most obvious way of
ensuring that all circuits and
equipment which are being worked
on are proved to be dead is to lock
off a circuit and ensure no live
source exists by means of a voltage
indicator but how do you know
your voltage indicator is
performing correctly?
Martindale Electric suggests the
only way to offer complete peace of
mind is to check your tester before
and after with a Proving Unit such
as its PD700.
